N-alkylester N-substituted heterocyclic diazo aryl amine

Particle size distribution (Granulometry)

Description of key information

The mean particle size of the milled test item (milled press cake for testing purposes) was determined to be 42.7 µm with a 90% range of 2.8 to 292.1 µm; whereas the mean particle size of the imported and marketed product is determined to be 150.8 µm with a 90% range of 56.35 to 245 µm.

Additional information

The particle size of the dedusted dye product of Disperse Blue CVG, which is part of the dye product of the test item as imported and marketed, was determined at its production site by laser diffraction (light scattering).

The median particle size L₅₀(D (v, 0.5): 50 % of particle volume or particle mass with lower particle diameter) deduced from these distributions are: L₅₀ = 150.8 µm

The particle size L₁₀(D (v, 0.1): 10 % of particle volume or particle mass with lower particle diameter) deduced from these distributions are: L₁₀= 56.35 µm

The particle size L₉₀(D (v, 0.9): 90 % of particle volume or particle mass with lower particle diameter) deduced from these distributions are: L₉₀= 245 µm

The particle size distribution of the test item that was milled for testing purposes was determined by laser diffraction (light scattering).

The median particle size L₅₀of the test item deduced from the particle size distributions was 42.7 µm.

The particle size L₁₀of the test item deduced from the particle size distributions was 2.8 µm.

The particle size L₉₀of the test item deduced from the particle size distributions was 292.1 µm.
